Re: brake squeal?
Same thing happened to me, also at about 600-1000 miles. Squealing at stops, etc, just like you describe. Did the hard braking thing at speed (as recommended by my dealer as well). The squeals went away really on their own (I'm not sure the hard braking really did anything), and I only occasionally now hear them (I have 3500 miles on my S Cab). If they get worse = dealer visit. I suspect they will get better by themselves.
